The aviation industry experienced a rapid transformation following deregulation. Several low-cost carriers entered the Indian market in 2004–05. Major new entrants included Air Deccan, Air Sahara, Kingfisher Airlines, SpiceJet, GoAir, Paramount Airways and IndiGo. Kingfisher Airlines became the first Indian air carrier on 15 June 2005 to order Airbus A380 aircraft worth US$3 billion.[199][200] However, Indian aviation would struggle due to an economic slowdown and rising fuel and operation costs. This led to consolidation, buyouts and discontinuations. In 2007, Air Sahara and Air Deccan were acquired by Jet Airways and Kingfisher Airlines respectively. Paramount Airways ceased operations in 2010 and Kingfisher shut down in 2012. Etihad Airways agreed to acquire a 24% stake in Jet Airways in 2013. AirAsia India, a low-cost carrier operating as a joint venture between Air Asia and Tata Sons launched in 2014. As of 2013–14, only IndiGo and GoAir were generating profits.[201][needs update]
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
